“Watch Your Head!,” by Dr. Randy Borum

“Sport-related concussions once again have hit the headlines. It is estimated that at least 300,000 of them occur every year. Martial artists who do full-contact sparring are certainly at some risk for these injuries. But are concussions really such a big deal? Medically, a concussion is considered to be a mild traumatic brain injury. It is caused either by some type of blunt trauma – such as a punch or kick- or by forces accelerating or decelerating the brain within the skull. Typically, there is no discernible damage to the structure of the brain, but concussions do temporarily disrupt brain functions.”
